Despite more than a century of coral reef research, the basic biology of reef corals remained poorly understood until the advent of scuba diving and the associated underwater technol-ogy that followed. Basic information such as the nature of the coral–algal symbiosis, the importance of coral heterotrophy, specialized structures for space competition, the role of mutualistic crustacean symbionts, the behavior and dispersal ability of coral larvae, the nature of coral protection from ultraviolet radiation and heat stress, and the effects of ocean currents and internal waves on reefs all beneted from the ability of scientists to spend time under water observing, making measurements, and carrying out experiments. In addition to enhancing our understanding of corals themselves, the ability to spend time under water has also provided a huge amount of information about coral reef ecosystems and their component species. These benets were further enhanced by new opportunities for saturation ...

Labroid fishes include a variety of families, such as wrasses (Labridae), odacids (Odacidae), damselfishes (Pomacentridae), parrotfishes (Scaridae), cichlids (Cichlidae), and surfperches (Embiotocidae). With only 23 species, the small embiotocid family exhibits a remarkably low species diversity compared to the large species diversity of the Cichlidae. Using mitochondrial DNA sequences of all 14 extant embiotocid genera, we established a molecular phylogeny of the family and compared it with a previously proposed morphological phylogeny. Genetic differentiation among embiotocids was compared to that among cichlids. Although species numbers are extremely different between these two families, the degrees of genetic differentiation within each family was found to be very similar.

Dispersal in marine species results from complex interactions between biotic and abiotic factors. Importantly, the pelagic larval phase of most marine species adds a significant degree of complexity. Therefore, a growing body of work is focusing on those rare species that lack a pelagic larval phase (usually brooding species). For such species, large-scale gene flow has been shown to be very low, thus following the expectation of a relationship between realized dispersal and pelagic larval duration. Yet, little is known about the dispersal of those species at very small geographic scales. In this study, we focused on the Banggai Cardinalfish, Pterapogon kauderni, a mouthbrooding species that lacks a pelagic larval phase. Based on previously identified microsatellites, we scored 12 populations around the southern island of Bangkulu, in the Banggai Archipelago, Indonesia. While only 60 km in perimeter, we found that this island harbors very distinct populations of P. kauderni. Indeed, assignment tests self-assigned 10 out of those 12 populations. These results mirror the very high level of self-assignment at the level of the entire archipelago, where, out of 13 populations, 70% of the individuals were reassigned to their source population. Therefore, our data show consistency between small and large-scale dispersal. In addition, in light of the recent expansion in the harvesting of this species for the pet trade, our data have important conservation implications.
